摘要
Methods and systems for finite impulse response filter under a constrained sampling rate. A method for constrained sampling rate filtering includes segmenting an input signal with a first rate into a defined number of streams, wherein the defined number of streams sets an effective sample rate of each stream to at least less than a second rate and the second rate is less than the first rate, determining filter coefficients for a finite impulse response filter, grouping the filter coefficients into subsets of filter coefficients to match the defined number of streams, applying in parallel, for each of the defined number of streams, a subset of filter coefficients to a corresponding stream, and combining at least some outputs from the defined number of streams conditionally based on the second rate.
